G01S 13/00 Systems using the reflection or reradiation of radio waves, e.g. radar systems; Analogous systems using reflection or reradiation of waves whose nature or wavelength is irrelevant or unspecified
Introduced: January 1980
Description
G01S13/00 is the main group for systems that use the reflection or reradiation of radio waves to determine position, distance, velocity or presence of objects, i.e. radar systems, together with analogous systems whose wave nature is irrelevant or unspecified. It covers pulse, continuous-wave and frequency-modulated radar, secondary radar with transponders, and moving-target indication. Application fields range from air traffic control and marine navigation to automotive driver assistance and ground-penetrating survey. Analogous systems using acoustic or optical waves are classified in G01S15/00 and G01S17/00.
Of 8 combined children, 6 exist in both systems.
2 codes are CPC-only extensions.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 1980.
